Modifier and Type | Method and Description |
---|---|
void |
delete(OpenJPAStateManager sm,
JDBCStore store,
RowManager rm)
Set the where values appropriately to delete the proper instance,
and set all relations on non-secondary tables as updates.
|
Column[] |
getKeyColumns(ClassMapping cls)
Return the columns holding data for a map key for the given key mapping
from
LRSMapFieldStrategy.getIndependentKeyMappings(boolean) or
LRSMapFieldStrategy.getIndependentValueMappings(boolean) (or null). |
Result[] |
getResults(OpenJPAStateManager sm,
JDBCStore store,
JDBCFetchConfiguration fetch,
int eagerMode,
Joins[] resJoins,
boolean lrs)
Return results containing all keys and values for this map.
|
Column[] |
getValueColumns(ClassMapping cls)
Return the columns holding data for a map value for the given value
mapping from
LRSMapFieldStrategy.getIndependentKeyMappings(boolean) or
LRSMapFieldStrategy.getIndependentValueMappings(boolean) (or null). |
void |
initialize()
Perform caching and other initialization operations.
|
void |
insert(OpenJPAStateManager sm,
JDBCStore store,
RowManager rm)
Set values for the mapping into the proper rows.
|
Joins |
joinKeyRelation(Joins joins,
boolean forceOuter,
boolean traverse)
Join this value's table to the table for the related first class object
key type, if any.
|
Joins |
joinKeyRelation(Joins joins,
ClassMapping key)
|
Joins |
joinRelation(Joins joins,
boolean forceOuter,
boolean traverse)
Join this value's table to the table for the related first class object
type, if any.
|
Joins |
joinValueRelation(Joins joins,
ClassMapping val)
Invokes
FieldStrategy.joinRelation(org.apache.openjpa.jdbc.sql.Joins, boolean, boolean) by default. |
Object |
loadKey(OpenJPAStateManager sm,
JDBCStore store,
JDBCFetchConfiguration fetch,
Result res,
Joins joins)
Load a key from the given result.
|
Object |
loadValue(OpenJPAStateManager sm,
JDBCStore store,
JDBCFetchConfiguration fetch,
Result res,
Joins joins)
Load a value from the given result.
|
void |
map(boolean adapt)
Map the owning mapping using this strategy.
|
void |
selectKey(Select sel,
ClassMapping key,
OpenJPAStateManager sm,
JDBCStore store,
JDBCFetchConfiguration fetch,
Joins joins)
Implement this method to select the keys of this field.
|
void |
selectValue(Select sel,
ClassMapping val,
OpenJPAStateManager sm,
JDBCStore store,
JDBCFetchConfiguration fetch,
Joins joins)
Implement this method to select the values of this field.
|
Object |
toDataStoreValue(Object val,
JDBCStore store)
Translate the given external field value to its datastore equivalent.
|
Object |
toKeyDataStoreValue(Object val,
JDBCStore store)
Translate the given key value to its datastore equivalent.
|
void |
update(OpenJPAStateManager sm,
JDBCStore store,
RowManager rm)
Set values for the mapping into the proper rows.
